Welcome

A Structural View of Biology

This resource is powered by the Protein Data Bank archive-information about the 3D shapes of proteins, nucleic acids, and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease.

As a member of the wwPDB, the RCSB PDB curates and annotates PDB data.

The RCSB PDB builds upon the data by creating tools and resources for research and education in molecular biology, structural biology, computational biology, and beyond.

Use this website to access curated and integrated biological macromolecular information in the context of function, biological processes, evolution, pathways, and disease states.

3D Structure: Jmol

The Jmol molecular viewer offers several options for display and analysis.
Launch the viewer using the 3D View feature from any entry's Structure Summary or by entering an ID below. Learn more about Jmol.

Sequence & Structure Alignment

Comparisons can be made for any protein in the PDB archive and for customized or local files not in the PDB.
Special features include support for both rigid-body and flexible alignments and detection of circular permutations.

Protein Structure Initiative Featured System

Each of our cells contains a complete factory for building proteins, including the machinery for building the component amino acids and for linking them up according to information in the genome. There is also an effective system for quality control, to ensure that these proteins fold in the proper way and are discarded efficiently when their jobs are finished.... Read More

Molecule of the Month

Scientists have known for many years that plants respond to light, growing toward sources of light and protecting themselves from light that is too harsh. In many of these cases, plants are responding to the level of blue light. Blue light has several advantages over other colors. It is among the most energetic of the visible colors, and thus can have a greater... Read More
